Sure, words will always have fuzziness, but there is benefit to substituting fuzzy terms with clearer terms. Words help influence thinking, so fuzzy words can lead to fuzzy thinking.

If we are debating an API design and a colleague says "it's too much magic", is that bad thing? If I write deliverEmail(email) and the e-mail "magically" gets sent, what's wrong with that?

On the other hand, if we debate the abstraction itself--for example behavior doesn't match user expectations--then we can do better at improving the API design.
